Hi,

I would like to run some simple benchmarks on an embedded device with an architecture that does not support valgrind.
For my purposes, something like the the QElapsedTimer would be sufficient, unfortunately, the Qt version on the device is too old, and cannot be upgraded easily.

What would be a viable alternative to using QElapsedTimer that would work with Qt 4.6.3 ?

Thanks!

You could use QTime with msecsTo().

Or with elapsed()

the right pattern seems to be:

#if (QT_VERSION < QT_VERSION_CHECK(4, 7, 0))
# include <QTime>
typedef QTime QElapsedTimer;
#else
# include <QElapsedTimer>
#endif
